'WlNDlNG-SHELL FOR CALlCO, 80c.

SPECIFICATION forming part of Letters Patent No. 267,817, dated November21, 1882,

Application filed April 11, 1882. (No model.)

of Passaic, in the county of Passaic and State of New Jersey, haveinvented a new and 1111- proved Winding-Shell for Calico, 850., of whichthe following is a specification.

My invention relates to the hollow wooden shells which are used forwinding long strips of calico, cotton cloth, or other fabric or paper,or similar material into large rolls; and'it consists of a metal castingconsisting of a central .portion which has a square passage through itand a surrounding ring or ferrule connected to the central portion byfins, the casting to be forced into the ends ofthe shell forstrengthening the same anddor furnishing a metal socket, bushing, orclutch for connecting the ordinary power-shank for revolving the shell.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l isfla central sectional elevation of an ordinary woodenwindingshell having my metal bushing and ferrule applied thereto; andFig. 2 is an end elevation of the same.

A represents the wooden winding shell, which is of the ordinary form andconstruction and B B represent the castings or bushing applied to theends thereof. The central portion, a, of the casting or bushing is bypreference deeper than the surrounding ring I), and is of an externalsize equal to ora little greater than the bore of the shell A, and hasthe square central passage, f, through it, as shown clearly in Fig. 2.The surrounding ring I), which formsthe ferrule part of the casting, isjoined to the central'portion, a, by the radial line 0 c, which are bypreference made slightly tapering from their outer to their inner edges.The ring D is also made slightly tapering from its outer to its inneredge, as shown in Fig. 1, to facilitate the driving or forcing of thecasting into the ends of the shell. The castings will be forced bysuitable power into the ends of the winding-shell before the shellisputinto the lathe to be turned up, and suitably attached to thelathe-dogs for turning, so that nishes a clutch for the square shank.The ring b, when the castings are forced into the shell, inclosesand toaconsiderable extentcompresses the portions d d of'the material of theshell between the ring and the central portion, a, of the casting, andacts as a ferrule to those portions, thus adding greatly to the strengthand durability of the shell.

In order to strengthen the fins c c and to facilitate the removal of thepattern in the casting of the device, I prefer to re-enforce the fins atthe corner where theyjoin the ring I) and central portion, a, as shownat i t in Fig. 2.

Having thus fully described-my invention, I claim as new and desireptosecure by Letters Patent .7

'1. As a new article of manufacture, a combined bushing and ferrule forwinding-shells,

consisting of the central portion, a, having a square hole,f, thetapering rim 1), and the tapering fins 0, connecting the rim and centralportion together, the said central portion being deeper than the rim,substantially as herein shown and described.

2. The combination, with the shell A, of the casting B, consisting ofthe apertured central portion, a, the tapering rim 0, and the taperingfins a, connecting the central portion and rim together substantially asherein shown and described, whereby the casting serves the doublepurpose of a bushing for the shell and means for securing it in a lathefor turning up saidv shell, as set forth.
